Cells . 2025 Jan; 14(1. PMID: 39791709
Chromosomal abnormalities of the embryo are the most common cause of first-trimester pregnancy loss. In this single-center study, we assessed the frequency and the spectrum of chromosomal abnormalities in miscarriages...

J Clin Med . 2024 Jun; 13(11). PMID: 38893001
In recent years, preimplantation genetic testing for aneuploidies (PGT-A) has become widespread in assisted reproduction. However, contrary to expectations, PGT-A does not significantly improve the clinical outcomes of assisted reproductive...

Int J Mol Sci . 2023 Jul; 24(13). PMID: 37445605
Predicting the clinical outcomes of intracytoplasmic sperm injection (ICSI) cycles that use the testicular spermatozoa of azoospermic patients presents a challenge. Thus, the development of additional approaches to assessing the...

Genes (Basel) . 2023 Apr; 14(4). PMID: 37107671
We report on the case of prenatal detection of trisomy 2 in placental biopsy and further algorithm of genetic counseling and testing. A 29-year-old woman with first-trimester biochemical markers refused...

Krapivin M, Tikhonov A, Efimova O, Pendina A, Smirnova A, Chiryaeva O, et al.
Int J Mol Sci . 2021 Jul; 22(12). PMID: 34205622
The present study investigates telomere length (TL) in dividing chorionic cytotrophoblast cells from karyotypically normal and abnormal first trimester miscarriages and ongoing pregnancies. Using Q-FISH, we measured relative TLs in...

Pendina A, Krapivin M, Efimova O, Tikhonov A, Mekina I, Komarova E, et al.
Int J Mol Sci . 2021 Jun; 22(11). PMID: 34070406
The human lifespan is strongly influenced by telomere length (TL) which is defined in a zygote-when two highly specialised haploid cells form a new diploid organism. Although TL is a...

Int J Mol Sci . 2020 May; 21(9). PMID: 32370155
Convincing evidence accumulated over the last decades demonstrates the crucial role of epigenetic modifications for mammalian genome regulation and its flexibility. DNA methylation and demethylation is a key mechanism of...

5-hydroxymethylcytosine (5hmC) is an oxidative derivative of 5-methylcytosine (5mC). Recent studies have revealed a sharp difference in the levels of 5hmC in 2 opposite DNA strands of a given chromosome...
